It has three disadvantages: It leaks in long-continued wet weather; it drops down dust and dirt in dry weather; and is so heavy that it usually ends by crushing in the log rafters and beams, unless they are further supported on posts, which are much in the way.

But its advantages were so obvious that the builders did not hesitate.

A clay roof it was to be.
When the walls were five feet high, the doorway and window were cut through the logs, but leaving in each case one half of the log at the bottom of the needed opening.

The top log was now placed, then rolled over bottom up, while half of its thickness was cut away to fit over the door: a similar cut out was made over the window.

Two flat pieces of spruce were prepared for door jambs and two shorter ones for window jambs.
